Audio data processing method, apparatus and device, and storage medium

An audio data processing apparatus, comprising:

• an information acquisition module, which is configured to acquire audio data to be processed and a variable-speed rate of at least one audio frame in the audio data;
• a frequency domain conversion module, which is configured to sequentially use the at least one audio frame as a current audio frame to be processed and convert the current audio frame to a frequency domain;
• an audio processing module, which is configured to determine a target phase signal of the current audio frame according to a variable-speed rate of the current audio frame and a variable-speed rate of a previous audio frame;
• and
• a result acquisition module, which is configured to perform, according to the target phase signal, time domain conversion on the current audio frame converted to the frequency domain to obtain a processed current audio frame.
